Parts that can be easily obtained for killerjackalope's jet engine. Includes body of jet, and the jet nozzel(probably not as good as what he is thinkin up )

Step 1: Materials

Ok, what you need is:

an old R/C car controler
needlenose pliers
a small hole puncher
screwdriver
old airsoft gun(or new cheap one)

Step 2: Break Antenna

First you need to break the antenna off, this will be what you use to make the jet nozzel.
then you have to poke four small and i stress small holes in the sides near the end. Then you have to make a "v" shape with the needle nos pliers at the end. This may be difficult to do depending on the metal it is made of. its should look like it does in the third pic below. you may want to leave a small gap between the bases to allow a little gas through, it is optional though, and i have not had any benifits from it.

Step 3: The Barrel

All you have to do for this is take apart the airsoft gun any way you want and remove the metal barrel from the gun. best to use a clear gun so you know it has one too, dont want to ruin a good gun. this will be the body of the jet and it works great too! can be cut down if its too long, and if its even bigger you could even make two with it!
